Advanced search

Advanced search is divided into two main parts, and one or more groups in each of the main parts. The main parts are the "Search for" (including) and the "Remove from search" (excluding) part. (The excluding part might not be visible until you hit "NOT" for the first time.) You can add new groups to both the including and the excluding part by using the buttons "OR" or "NOT" respectively, and you can add more search options to all groups through the drop down menu on the last row (in each group).

For a result to be included in the search result, is it required to fit all added including parameters (in at least one group) and not fit all parameters in one of the excluding groups. This system with the two main parts and their groups makes it possible to combine two (or more) distinct searches into one search result, while being flexible in removing results from the final list.

This book provides a detailed description of what long products are, how they are classified, how they are produced, as well as the types of equipment that produce long products. The volume provides a comprehensive overview of long product production from describing the roll pass design, to the different shapes and sections, to the manufacturing of wire and wire products, to tubular products, and finally to high-alloy steel semi-finished products by casting and ingots.

Cibes Lift AB sells personal lifts and currently uses full-scale elevators for demonstration, for example at fairs. Now they want to come up with a mini-elevator that will facilitate the work of demonstrating the Cibes A5000 and also demonstrate the installation of screen walls, which is not possible with the full-scale elevator since the risk of accidents are high and the installation is permanent by pop rivets. In order to facilitate the work, systematic methods were developed to get a clear picture of the course of action, starting with a zero-state analysis of the problem to later immerse ourself in the subject of miniature models using a literature study. Subsequently, interviews and all data from the work were compiled and reviewed with the quality house method to create measurable criteria that could facilitate the draft proposals and the design phase. A risk analysis was also made with regard to constructing a safe product. Once the concepts were completed, one of them was chosen by Cibes. Forthgoing the construction of the elevator was broken down into modules to allow the work to be easily distributed. The result of the work is a construction of a 1:3 scale miniture lift that is capable of demonstrating operation between two floors and display the inner workings of liftsystem propulsions system and installation of a screen wall. The strength of the construction is calculated for the possible impact of a person that the miniature model can be subjected to. And a risk analysis was conducted to facilitate the construction of a safe product. Something that the project would have benefited from is that the zero-state analysis of the design would have been done at an earlier stage to facilitate scheduling and predict any help that might have been needed or knowledge that could be learned before work commenced.
